IFX25001TFV33ATMA1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The IFX25001TFV33ATMA1 is a discontinued positive fixed linear low-dropout (LDO) voltage regulator manufactured by Infineon Technologies. It provides a fixed 3.3V output with a maximum continuous current of 400mA. The device supports an input voltage range up to 40V and features a typical quiescent current of 220 µA. Key electrical specifications include a maximum dropout voltage of 1.2V at 300mA load and a power supply rejection ratio (PSRR) of 60dB at 100Hz. It is housed in a PG-TO252-3 surface-mount package and operates within a temperature range of -40°C to 125°C.
